A charged particle moving through a medium emits Cherenkov radiation when its velocity exceeds the phase velocity of light in that medium. Under the influence of a strong electromagnetic field, quantum fluctuations can become polarized, imbuing the vacuum with an effective anisotropic refractive index and allowing the possibility of Cherenkov radiation from the quantum vacuum. We analyze the properties of this vacuum Cherenkov radiation in strong laser pulses and the magnetic field around a…

Synergic Cherenkov-Compton radiation
In vacuum with an induced by strong electromagnetic wave refraction index larger than unity, an ultra-relativistic electron emits Cherenkov radiation. During the interaction with this wave the
Electromagnetic solitons in quantum vacuum
In the limit of extremely intense electromagnetic fields the Maxwell equations are modified due to the photon-photon scattering that makes the vacuum refraction index depend on the field amplitude.
Cherenkov Radiation Effect in Vacuum
The Cherenkov effect usually occurs in a certain medium. In this medium, such as water, the speed of particles exceeds the speed of light in the medium, which will produce observable Cherenkov
Cherenkov radiation and photo-pair production in a strong magnetic field
According to quantum electrodynamics, in a strong magnetic field that is constant and spatially uniform, the vacuum becomes polarized with a refractive index greater than unity. As a result,

We discuss in this paper the vacuum Cherenkov radiation in the z = 2 Lifshitz electrodynamics. The improved ultraviolet behavior, in terms of higher spatial derivatives, and the renormalizable
Experiment to observe an optically induced change of the vacuum index
Quantum electrodynamics predicts that the vacuum must behave as a nonlinear optical medium: the speed of light should be modified when the vacuum is stressed by intense electromagnetic fields. This
The coherence of light is fundamentally tied to the quantum coherence of the emitting particle
This work uses quantum electrodynamics to show how the particle’s momentum uncertainty determines the optical coherence of the emitted light and proposes new Cherenkov detection schemes, whereby measuring spectral photon autocorrelations can unveil the wave function structure of any charged high-energy particle.
\v{C}erenkov radiation in vacuum from a superluminal grating
Nothing can physically travel faster than light in vacuum. This is why it has been considered that there is no Čerenkov radiation (ČR) without an effective refractive index due to some background

Abstract The first demonstration of laser action in ruby was made in 1960 by T. H. Maiman of Hughes Research Laboratories, USA. Many laboratories worldwide began the search for lasers using different
Causality test on Cherenkov effect in circuit QED
We investigate the Cherenkov radiation triggered by qubit acceleration simulated by superconducting circuit. By analyzing the radiation probability, we confirm the existence of Cherenkov speed


Cherenkov radiation in a photon gas
It is well known that a charged particle moving with constant velocity in vacuum does not radiate. In a medium, the situation can be different. If the so-called Cherenkov condition is satisfied, i.e.
